Does this fuel Economy seem correct?

[dhman06]

Since I am going to around a lot this summer, I wanted to see how is the fuel economy for my 1999 Toyota Camry. I bought 11.28 gallons of oil about a week ago when I had 75% of fuel left and to check the fuel economy I reset the trip meter. Now that my fuel is about at 75% I figured it would be a good time to see what mpg I get. From the trip meter readings (since there is A and B) I got 420 miles for 11.28 gallons. That means I am getting around 37 MPG highway and city combined. Does it seem correct? Anyway getting close to that?

37 MPG seems not possible without aero mods even on highway only when using fuel saving techniques.

1. reset the trip meter when refilling thank
2. take a receipt which says how many gallons went into tank to fill it up.
3. drive it for a week (or 300 miles or so) and write down whatever the trip meter shows at gas station then repeat step 1 & 2.

then you simply divide miles you drive (from the trip meter) by a number of gallons which were used (from last gas refill receipt).

ecomodders.com you can make an account and they have tracking and you can join in the camry aero modding thread and they have tips

also i have done this pure highway on my mz drafting

Thanks for the advice guys. Let me follow the instructions provided and I will get back to you guys in couple of days.

Okay, This is my second reading---

I purchased 12 gallons of gas and from the trip meter readings I got 230.6+230.6 (Total 461.2 miles). That means my MPG is somewhere around 37 or 38 (city and highway combined). Why am I getting so high numbers?

Are you ADDING both trip meter readings? You have two trip meters, A and B, but they are two independant meters. If you use A and B and reset both when you fuel up, the mileage driven is recorded on both, but you don't add them together. Use the number on one OR the other. 230.6 miles divided by 12 US gallons = 19.2 US mpg......which is about right.

I think you're adding up the trip meter readings in both A and B. If you divide that into 2, that would give you 19 mpg, a bit low for a 4 cylinder, not too bad if you're using a 6 and have a lead foot, and due 50% city driving. When I drive 50% city driving, including sitting in traffic on the highway, I get get about 26-28 mpg on a four. The best I have done is 37 mpg, cruising at about 65 mph for 300 miles from Dallas to Houston with the AC on, but that's rare. When I did mostly highway commute in the summer last year, my car was getting 30-32 consistently

[dhman06]

Well, since I reset the trip meter when I refill, shouldn't I count both of my trip meter numbers? I mean afterall both of those trip meters read the mileage that is recorded using the refilled fuel.

[fenixus]

those meters are both inclusive, meaning you cannot add both of them. when you travel 10 miles it will get reflected in both trip A and trip B meters. use only one trip meter (either one) otherwise you will be falsely doubling the mileage.

[redtigerrocks]

It's HIGHLY impossible to have a 37 MPG. The max is probably 32-33 if you good on the foot and your car is well maintained.

my old beat up 93 4cyl camry stick shift with 300k miles on odometer still manage to do 30 to 32 mpg in summer with mix 15% local, 85% higheway traffic. in winter, i only get about 28pmg during winter.
one tank of gas normally yield average 450 miles before i need about about 14 to 15 gallon of refill.
